Issued in 1944 to mark the birth centenary (1844–1944) of Ribeiro de Andrada, this 40 réis blue commemorative honors one of Brazil’s notable political and intellectual figures. The finely engraved portrait is framed by bold “Brasil Correio” typography, giving the stamp a strong classical 1940s aesthetic. Its single-color steel engraving highlights delicate facial shading and line work prized by traditional collectors. A representative mid-20th-century Brazilian commemorative, it fits well in history, statesman, and Latin America collections. Clean examples with sharp perforations and fresh color are especially desirable.
